The Discriminating Beta: Prices and Capacity with Correlated Demands

Uniform customer‐class pricing can do much of the work of congestion‐based or time‐of‐day pricing in communication or wireless networks. A monopolist exploits differences in the stochastic characteristics of demands. If demands are correlated and the firm faces a capacity constraint, then it can set prices to reduce the variability of aggregate demand, thereby reducing the probability of excess demand and the associated service quality deterioration. Demands that covary negatively with aggregate demand are valuable to the firm in much the same way that securities that covary negatively with the market are valuable in a stock portfolio. Customer classes that exhibit low covariance with aggregate demand realize lower optimal prices. Optimal capacity is also affected by these covariances. As long as demands are not perfectly positively correlated, expected costs of joint production are less than expected costs of serving demands separately.     

Firm Heterogeneity and Export Pricing in India

We examine export pricing by Indian manufacturing firms in the early 2000s using a unique data set that matches firm characteristics with product and destination‐level trade data. We find that, in contrast to China and other countries, firm productivity is negatively associated with export prices, and export prices are negatively associated with distance while positively associated with remoteness. Our conjecture is that Indian innovation costs, which are higher than China's, drive down the scope for quality differentiation causing a negative association between productivity and prices. To the best of our knowledge, this is the first empirical evidence consistent with heterogenous goods and short quality ladders, a theoretical possibility noted in the study by Antoniades (2012), an outcome that arises here because of domestic Indian economic and regulatory features.     

Collusion,entry, and market shares

This paper analyzes market entry and collusion in a model of duopoly with product-specific-set-up costs. The analysis demonstrates that collusion can alter the incentives for entry deterrence. We find conditions under which an established firm will permit entry and collude with a potential entrant even though entry deterrence is a viable option under noncooperative oligopoly rules. Conditions are also specified in which entry will be effectively impeded and collusion will not be undertaken.     

Performance signals in the public sector: the case of health care

Although there are no traditional markets and money prices inthe public sector, consumers and providers may respond to signalsof organisational performance. We present a simple dynamic modelof the demand and supply for elective surgery in the UK NationalHealth Service in which waiting time acts as the prime indicatorof performance. The model is tested using a panel of quarterlydata for 123 English health authorities over an eight-year period.We find that supply is increasing and demand is decreasing inmeasures of the previous period waiting time. The results implythat health care systems which are rationed by waiting do respondto indicators of waiting times. The paper adds to the smallbut consistent body of research which demonstrates that publicsector systems respond to important aspects of reported performance.     

Regaining Missed Opportunities: The Role of Tourism in Post-war Development in Sri Lanka

Sri Lanka had the opportunity to become one of the best tourism countries (TCs) in Asia immediately after independence in 1948. However, it missed opportunities on a number of occasions due to inappropriate economic policies, continuous political violence and war. Between 1983 and May 2009 the Sri Lankan tourism sector was seriously affected by nearly three decades of separatist war. Immediately after the end of the war, tourism in Sri Lanka bounced back and it has now become one of the main engines of economic growth in post-war Sri Lanka. In this article, a historical analysis has been undertaken to demonstrate how, despite its large tourism potential, Sri Lanka missed opportunities and fell far behind its Asian counterparts on a number of occasions. This article demonstrates that opportunities exist for the Sri Lankan tourism sector to play a vital role in the current post-war inclusive development strategy in terms of generating much needed foreign exchange, poverty alleviation via employment generation, accelerating economic growth and uplifting living standards of all Sri Lankans.
